    ScanProtect is an enhanced warranty specifically designed and offered by Scan to reduce the risk of any mishap or damage to components during installation.

Product Overview The new Seasonic X-Series is a slightly improved version of the initial X-Series, which was the very first fully modular multi-output, high-wattage ATX power supply that has ever obtained the 80PLUS® Gold certification.

Featuring a patent pending design of DC Connector Module with Integrated VRM, the X Series is set to achieve near-perfect DC to DC conversion and a fully modularized design without compromising efficiency. This top-class PSU delivers the complete package, ultra-high efficiency, greatly improved dynamic response, and customizable cable arrangement that can be tailored to meet any individual’s needs.

The Seasonic X Series adopts a clever Hybrid Silent Fan Control design, which offers three distinct operation modes, Fanless Mode, Silent Mode, and Cooling Mode. The control automatically adjusts the fan mode and its speed according to the ambient temperature level. This creative design not only optimizes heat dissipation, but also prolongs the lifespan of the system by reducing unnecessary fan rotation. To make the X Series even more robust and exciting, Seasonic offers Sanyo Denki San Ace PWM Silent Fan, the best fan there is in the industry with pulse-width modulation.

The X Series represents the Green PC technology that helps computer users save on their electricity bill. It achieves the 80PLUS® Gold standard that guarantees an above 87% efficiency rating across 20%, 50% and 100% loading along with a true power factor of >0.9. Moreover, the X Series is compliant with the Energy Star 5.0 rating and reduces energy consumption under standby, sleep and idle modes.

750W Seasonic X-Series, Full Modular, 80PLUS Gold, ATX, PSU is rated 4.9 out of 5 by 8.
Rated 5 out of 5 by from 750W of quality in a black velvet bag Overall, very impressed with this. I wanted a 160mm PSU to fit my mITX case, and this fit the bill perfectly. Seasonic make a quality product (they make Corsair's PSUs for them). Comes with plenty of cables, only criticism is that they are quite stiff which can make cable management tricky. Good build quality throughout, is very quiet and runs nice and cool. The presentation in the box really makes this - it even comes in a black velvet bag! It's a small touch, but I can't say no to a classy product. Would recommend this to anyone needing 750W

Rated 5 out of 5 by from Compact and high quality psu Compact gold rated fully modular PSU. If you choose to run the psu in hybrid mode the fan will only kick in when it needs to. After 1 month of constant use, I don't think I've heard the fan ramp up even once. I've owned other seasonic psu that still work after 10 years so have high hopes that this unit stand the test of time.

Rated 5 out of 5 by from Pricey but you get what you pay for As title, expensive but worth every penny. I have been chasing a buzzing / bleeping type noise around my 'silent' pc for a while. I have replaced CPU fan, graphics card fans, case fans and guess what? All the time it was my so-called silent PSU. Replaced it with this and SILENCE. The modular cabling is superb too, just use what you need, and a 7 year warranty. Highly recommended.

Rated 5 out of 5 by from Superb Power Supply I've used two of these supplies since 2010 and they have performed perfectly with no problems whatsoever. System stability is flawless and - as others have said - the fan seldom runs and is virtually silent when it does. Coupled with a fanless graphics card and decent i5 processor/fan combination I have a very decent desktop system driving a 30" moinitor that is usually completely silent. Buying today I would probably get the 760W platinum version but whichever one is chosen I would highly recommend Seasonic.

Rated 5 out of 5 by from the best after using a corsair hx 1000 which sadly gave up the ghost I done some reseach into psu,s and this make came in @ the best you can buy. admitidly ive only had it for a few days and all seems to be very efficient and very quite. coupled with a 7 year guarantee you cant go wrong.

Rated 4 out of 5 by from Silent Silent or 'barely audible' even under load. The motherboard power cables could have been a bit longer. Apart from that a very high quality product.

Rated 5 out of 5 by from Very good product, impressive product quality This is my first Seasonic power supply and I think I won't be needing a new one for a long long time... The build quality is superb and the unboxing experience is one of the kind.

Rated 5 out of 5 by from Top Quality You get what you pay for in PSUs, and what you pay for here is a top quality unit. With enough power to run most high end systems, this unit has a switch which offers both normal mode and a hybrid mode in which the fan doesn't switch on until the system is under 50% load. The result is that the unit is absolutely silent in most conditions (for a single graphics card system, it is unlikely to ever reach more than 50% load), and when the fan is running it is almost inaudible anyway. The unit is also highly efficient, not just in the middle of the load spectrum like many cheaper units but across a variety of load conditions. Add a seven-year warranty and this really can't be beaten.
